Abstract

Material such as cotton, containing motes, shives, or leaf is bleached by treating in a hot bath having added thereto an acid dye, an acid and an alkaline oxidizing agent. The preferred procedure is to wash the goods, say 100 lb., and pass them into a bath containing alkali blue, about 50 grains, at atmospheric temperature and leave them for 15 minutes. Acetic acid about 2 lb. is added and allowed to act for a further 10 minutes to develop the colour, after which the bath is brought to a high temperature, preferably 170-180 DEG F. About 7 lb. of the alkaline oxidizing agent is now added, such agent being preferably composed of about one half sodium peroxide and the other half caustic soda or a salt of an alkali metal, such as sodium chloride, soda ash, silicate of soda, phosphate of soda, or a mixture of these substances. The bath is maintained hot for a considerable time, such as an hour and a half. Specifications 103,445 and 158,531 are referred to.ALSO:Material such as cotton, containing motes, shives, or leaf is bleached by treating in a hot bath having added thereto an acid dye such as alkali blue, an acid, and an alkaline oxidizing agent.
